OUR COMPANY

YOUR DATA WHERE YOU WANT IT AND WHEN YOU WANT IT

The growing emphasis on ocean observing systems requires a wide spectrum

of technical solutions to support ocean data collection on a variety of spatial

and temporal scales, ranging from physical collection of samples by diver

or submersible, to long-term autonomous and remote monitoring of marine

environments. The latter is also driving a requirement for ever increasing

volumes of data direct to the shore for assimilation into models.

With a proven track record in the offshore energy industry, we also have an

enviable reputation for working closely with the world’s leading marine institutes

to adapt this know-how for ocean observation challenges. Today, we are able

to offer a variety of low-power sensing solutions designed for long term seabed

deployment, high bandwidth acoustic and optical telemetry, and optimised

communications and positioning solutions for unmanned underwater and

surface vehicles and other platforms.

MAXIMISING SCIENCE TIME, MINIMISING DOWNTIME

We know that scientists have to work hard to win funding, so when you finally

get to sea, you need to have technology that you can rely on to collect the data

you need efficiently and reliably. In these terms, you’re no different from our

customers in the offshore industry in demanding precision technology that

performs reliably in the most demanding environments 365/24/7, reduces costs

and enhances safety. And in case you do need us, we’re also here around the

clock to install, train and maintain.

SOLVING UNIQUE CHALLENGES

In many cases, vessels, underwater systems and operating environments are

unique. That’s why we’ll work with you even before you procure equipment to

fully understand your needs, and where standard off-the-shelf products cannot

meet your specific space, weight, depth and functionality demands, we have the

know-how and in-house resources to design, test and manufacture customised

RESEARCHVESSELS

ULTIMATE DP INTEGRITY

Out of the box, Ranger 2 Ultra-Short Baseline (USBL) provides stable and repeatable

acoustic position referencing for your ship’s Dynamic Positioning (DP) system,

including those from GE, Kongsberg, MT, Navis, Rolls-Royce and Wärtsilä. But if

you undertake critical station keeping activities close to offshore installations

or windfarms, where Global Navigation Satellite Systems (GNSS) can be unstable,

integration with our vessel-based inertial navigation technology (DP-INS) adds

enhanced levels of positioning integrity and resilience to GNSS outages.

LODESTAR ATTITUDE HEADING AND REFERENCE SYSTEM (AHRS)

Lodestar is a high performance, north-seeking gyrocompass and Attitude Heading

and Reference Systems (AHRS) that replaces the need for a separate Motion

Reference Unit (MRU) and gyro. It uses the same Ring Laser Gyros (RLG) and

accelerometers fitted to most commercial airliners and space exploration platforms,

so you can be assured of class-leading levels of performance and reliability. When

used with a Ranger 2 USBL system, overall system performance is improved by

optimising motion compensation – a configuration known as Optimised USBL.

SYRINX DOPPLER VELOCITY LOG (DVL)

Our hull-mounted Syrinx DVL measures high precision seabed-referenced velocity

speed over the ground in water depths ranging from less than one metre to

175 metres. Syrinx can also be used as a current profiler and/or used to measure

speed through the water. Thanks to its use of industry standard telegrams,

Syrinx is easy to install and interface with existing bridge navigation systems.

NAVIGATION AND OBSTACLE AVOIDANCE SONAR – NOAS

When your research takes you into uncharted waters, our forward-looking sonar,

NOAS, can help you see what lies ahead under the water and automatically warn

of hidden dangers. NOAS generates a geo-referenced 3D model of the seabed up

to 600 metres ahead of the vessel on the fly, which can be overlaid on a wide range

of electronic chart backdrops. Alerts based on depth, distance from the vessel and

estimated time to impact can be configured to warn of potential collision hazards.

RANGER2LODESTARAHRSSYRINXDVLNOASWE UNDERSTAND THAT RESEARCH VESSELS UNDERTAKE A WIDEVARIETY OF TASKS, OFTEN IN CHALLENGING ENVIRONMENTS ANDREMOTE LOCATIONS. TO SUPPORT THESE NEEDS, WE HAVE DEVELOPEDAN UNRIVALLED PORTFOLIO OF VESSEL-BASED TECHNOLOGIES THATUNDERPIN HIGH-PRECISION SENSOR OPERATION AND POSITIONING,WHILE OUR NAVIGATION AND OBSTACLE AVOIDANCE SONAR ISDESIGNED TO GIVE YOU THE CONFIDENCE TO OPERATE EVEN WHERETHE CHART IS LITERALLY BLANK.

SENSORPACKAGETRACKING

RANGER 2 – ACOUSTIC POSITIONNG AND COMMUNICATIONS FLEXIBILITY

Science users rarely have the luxury of remaining on site for long, so the ability

to position and communicate with submersibles and instruments, such as corers,

camera platforms and geological drills, without having to first deploy a seabed

array of transponders, helps maximise your precious ship time. To meet these

needs, our Ranger 2 USBL acoustic tracking technology is a highly capable and

flexible system that can track multiple underwater targets. At the same time,

it can communicate with, and remotely configure, seabed instruments such as

our Autonomous Monitoring Transponder (AMT). It can even be used to activate

our range of acoustic Release Transponders (RT 6), allowing you to release and

track your moorings all the way to the surface for recovery on board.

LONG RANGE TRACKING

With science projects being among our most demanding for deep and/or long

range tracking, we offer several innovative solutions to meet your needs. Our

Lower Medium Frequency (LMF 14 – 19.5 kHz) Ranger 2 systems have proven

tracking capability to beyond 11,000 metres range, while Inverted USBL (iUSBL)

combines a vehicle-mounted USBL transceiver with our Lodestar AHRS in the

same unit – providing a calibration-free solution for long layback tracking of towed

bodies at high elevations. By mounting the iUSBL system on the towed platform,

the system is able to benefit from lower noise levels than close to the ship,

enabling much longer tracking ranges to be achieved.

TRANSCEIVER ARRAY SOLUTIONS TO MEET YOUR NEEDS

Our USBL transceiver, called HPT, is available in a range of different designs to

suit your vessel, operating environment and task in hand. If your research involves

using a vessel of opportunity, then the benefits of using Ranger 2 begin before

you’ve even left port. Our pre-calibrated, all-in-one GyroUSBL transceiver is perfect

for installation on a temporary over-the-side mount or a USV, yet delivers the

same precision as a permanent installation.

TRANSPONDERS

The flexibility of the Ranger 2 family is further extended by our range of

transponders to support a wide variety of scientific missions. WMT is a high power

transponder capable of operations to 7,000 metres, while AvTrak 6 is our most

capable acoustic vehicle instrument, combining the functions of a USBL transponder,

LBL transceiver and modem for demanding applications such as AUV operations.

DEPLOYMENT OF SENSOR PLATFORMS AND UNDERWATER VEHICLESIS FUNDAMENTAL TO UNDERTAKING SCIENCE AT SEA AND RANGER 2IS THE PREFERRED CHOICE OF MANY OF THE WORLD’S LEADINGRESEARCH INSTITUTES TO POSITION THESE. IT’S MORE THAN JUSTA TRACKING SYSTEM THOUGH, WITH INTEGRATED HIGH SPEEDTELEMETRY CAPABILITY AND NOW COMPATIBILITY WITH OUR FAMILYOF ACOUSTIC RELEASES. THIS MEANS THAT RANGER 2 IS AT HOMEPOSITIONING A SEABED CORER AS IT IS AN AUV.

RANGER2LMFHPTTRANSPONDERS

WHY RANGER 2 USBL IS BEST

FOR TRACKING YOUR SENSORS

• Supports LMF for long range (>11km)and long layback tracking

• Built-in telemetry supports AUVs anddata harvesting from seabed sensors

• Compatible with a wide range of 6G transponders including RT 6

• ‘Out of the box’ operation on vessels of opportunity or USVs with GyroUSBL

• Simple and intuitive software

• Compatible with all DP systems

SHALLOWWATERTRACKING

MICRO-RANGER 2

Micro-Ranger 2 is an acoustic positioning system for tracking divers, remotely

operated and autonomous underwater vehicles. Portable and quick to mobilise,

it can be deployed from any waterside location or vessel-of-opportunity, including

RHIBs and small survey vessels. This makes it ideal for supporting science

operations conducted in rivers, lakes and coastal waters. The system has an

operating range of 995 metres and can update you with the position of each

target being tracked up to twice a second. If in time your projects demand more

capability, the system can be upgraded to Mini-Ranger 2 by exchanging the

Micro-Ranger Transceiver (MRT) for a HPT 3000 transceiver.

MINI-RANGER 2

Providing a standard 995 metres operating range, upgradeable to 4,000 metres,

Mini-Ranger 2 can track up to 10 targets simultaneously and is a compact system,

which is ideal for temporary installation on small vessels-of-opportunity, as well

as being suitable for permanent fit to a small research vessel. At the heart of

Mini-Ranger 2 is the HPT 3000 transceiver which is optimised for performance

in shallow water and at high elevation, as well as deeper water.

SIMLPLICITY OF OPERATION

Both systems have been designed to be easy to deploy and operate, reducing the

time that you need to mobilise a project. Key to this is the Ethernet Serial Hub,

which provides a single, but all encompassing, robust interface. This means

connection to a topside computer or ruggedised laptop is simple and user-friendly

– either directly or through a ship’s network via a single network socket. Ethernet

based communications also enable improved in-water diagnostics, permitting

the operator to both listen to, and visualise signals, and noise in the water.

TRANSPONDERS TO FIT YOUR PROJECT NEEDS

Micro and Mini-Ranger 2 are both compatible with our small USBL transponders,

ranging from Nano (weighing in at only 225 grams) to the popular Wideband

Sub-Mini 6+ (WSM 6+), as well as our MF Release Transponder 6s (RT 6). Options

to track AUVs using the Nano AvTrak 6 OEM are also available with the Robotics

Pack. Both systems are also capable of tracking aircraft ‘black box’ pinger locators.

WITH SMALL ROVS AND AUVS INCREASINGLY BEING USED INADDITION TO DIVERS FOR SCIENCE, THE ABILITY TO TRACK ANDCOMMUNICATE WITH THEM IS NOT JUST A QUESTION OF SAFETYAND EFFICIENCY, BUT ONE OF SCIENTIFIC VALUE WITH PRECISEGEOLOCATION OF SAMPLES OFTEN BEING CRITICAL. WITH OURSIXTH-GENERATION (6G) AND WIDEBAND 2 DIGITAL SIGNALTECHNOLOGY INSIDE, MICRO-RANGER 2 AND MINI-RANGER 2 COME WITH MANY OF THE CAPABILITIES THAT OUR USERS HAVECOME TO ASSOCIATE WITH THE RANGER 2 SYSTEM, BUT INSMALLER PACKAGES TO MEET THESE NEEDS.

MICROANDMINI-RANGER2

WHY CHOOSE MICRO AND MINI-

RANGER 2 TO TRACK YOUR TARGETS

• Cost-effective solutions for tracking divers, tow-bodies, ROVs and AUVs

• Portable and quick to mobilise

• Uses the same simple and intuitive software as Ranger 2 which can be installed on user’s own PC or laptop

• Compatible with a wide range of our mini-beacons, as well as aircraft locator beacons.

• Suitable for use on an AUV fitted with ourNano AvTrak 6 OEM using Robotics Pack

MARINEROBOTICS

LODESTAR AHRS AND SPRINT INS

With a track record spanning more than 10 years, our Lodestar AHRS meets the

needs of ROVs for mid-water station keeping, while SPRINT is a high quality INS

that improves the speed and efficiency of ROV and AUV operations. Aiding from

your vehicle’s DVL, pressure sensor, USBL or LBL acoustic system – even if it’s

from another vendor – can further improve performance.

Both are available with a choice of performance levels and by using the same

hardware platform, there is the ability to upgrade capability in the field. Lodestar

and SPRINT come in a standard 4,000 metre rated titanium housing (options for

6,000 metre) with on-board data and power backup, fast settling time and a range

of endcaps and connectors. An OEM version is also available for AUVs with

restricted payload space.

SYRINX DVL AND SPRINT-NAV

Syrinx meets the needs of users who require high integrity and high performance

navigation aiding over a variety of depths and seabed types. Operating at 600 kHz,

Syrinx works at altitudes comparable to a 300 kHz DVL, but has the high resolution

expected of a 1200 kHz DVL. Available in a variety of depth ratings and as an OEM

version, Syrinx has dual serial and Ethernet outputs, water blocked replaceable

transducers and because it’s made in the UK, is easy to export.

Syrinx integrated in a single housing with SPRINT becomes SPRINT-Nav, one of the

smallest inertial DVL instruments available on the market. Mechanical alignment

of the sensors improves the overall navigation performance and ensures a rapid

and simple mobilisation, while operations in rugged terrain are resistant to loss

of lock of one or two DVL beams due to tight beam-level integration with SPRINT.

AVTRAK 6

AvTrak 6 used in conjunction with Ranger 2 USBL systems is a versatile instrument

that combines the functions of transponder, transceiver and telemetry link in one

low power unit that has been designed to meet the requirements of a wide variety

of AUV mission scenarios and vehicle types. Available in three different sizes to

suit large and small AUVs, including man-portable variants, AvTrak 6 enables an

AUV to undertake simultaneous USBL tracking and telemetry with a surface

vessel, as well as AUV-to-AUV communications for swarm deployments.

INCREASING ENDURANCE AND CAPABILITY HAS RESULTED INMARINE AUTONOMOUS AND ROBOTIC SYSTEMS TRULY COMING OFAGE FOR SCIENTIFIC APPLICATIONS. HOWEVER, ONE SIZE DOESN’TFIT ALL AND THAT’S WHY OUR SUBSEA TECHNOLOGIES HAVE BEENDESIGNED TO BE COMPATIBLE WITH VEHICLES OF ALL SIZES ANDCAPABILITIES; FROM MICRO AUVS TO EXTRA-LARGE AUVS,AND EVERYTHING IN BETWEEN.

SUSTAINEDOCEANOBSERVATIONS

WITH AN INCREASING NEED FOR SENSORS TO BE DEPLOYED IN-SITUFOR MONTHS, IF NOT YEARS AT A TIME, THE DATA GATHERED BY THESESENSORS IS AS VALUABLE AS THE SENSOR ITSELF. CONSEQUENTLY,WE REALISE THAT THE RECOVERY OF BOTH IS VITALLY IMPORTANTTO YOU. FOR THE INSTRUMENT, THAT MEANS HAVING ACOUSTICRELEASES THAT YOU CAN RELY ON TO WORK LONG AFTER THE INITIALDEPLOYMENT; AND FOR THE DATA, THAT MEANS EFFICIENT ANDFLEXIBLE TELEMETRY SOLUTIONS.

ACOUSTICRELEASES&MODEMS

RELEASE TRANSPONDER 6 (RT 6)

Our new range of acoustic releases, RT 6, combines the extensive track record

of the previous models with the flexibility of our 6G platform, resulting in

compatibility with our Ranger 2 USBL family and enhanced battery life. With

release solutions for depths down to 6,000 metres and deployment life of up

to four years on alkaline batteries, we can support most scientific projects with

our standard off-the-shelf products. Our releases are most commonly used to

anchor oceanographic moorings to the seabed. However, their compact size and

compatibility with Ranger 2 makes them ideal for incorporation into instrument

frames or lowered platforms to enable deployment of sub-system packages.

MODEM 6

Whether you’re working in shallow or deep; quiet or noisy waters, our family

of Modem 6 instruments use our Wideband 2 spread spectrum digital signal

processing to provide reliable, bi-directional communications with data rates

between 100 and 9,000 bps. The technology is mature and low-risk with a track

record of operations from many different platforms, including long endurance

USVs which have demonstrated routine data harvesting from a network of our

Autonomous Monitoring Transponders (AMT) in depths in excess of 5,400 metres.

With over 500 unique addresses, you can also be assured that your operations

will not interfere with other operations that might be taking place nearby.

BLUECOMM

Increasingly though, acoustic telemetry systems just aren’t fast enough to transmit

the large amounts of data being collected by in-situ instruments. Until recently,

the only recourse has been to recover the instrument to a vessel, which is both

costly and time-consuming. Our high speed optical modem, BlueComm, changes

everything. Using rapidly modulating LEDs, a pair of BlueComm modems can

transfer large volumes of data at high speed (from 5 to 500 Mbps) over hundreds

of metres to one another – and do it all using very little power, making it ideal for

low-powered unmanned or autonomous platforms. Fitted with BlueComm, an

AUV can pass through an area of deployed data-logging instruments and harvest

their data quickly and efficiently. BlueComm is transforming the way we think

about access to subsea instrument data – it’s now possible to ‘connect’ your

subsea data back to your laboratory – without the costs of a cabled observatory.

WHY CHOOSE SONARDYNE TO

DEPLOY AND RECOVER YOUR DATA

• Highly reliable acoustic releaseswith long endurance capability and compatibility with Ranger 2 USBL

• Depth rated down to 6,000 metres

• Up to 9,000 bps acoustic telemetry available from our 6G product range

SEABED GEODESY

AUTONOMOUS MONITORING TRANSPONDER (AMT)

AMTs are are capable of recording hundreds of thousands of stable, highly precise

geodetic observations, safely log the data and on command, wirelessly transmit it

up to the surface. AMT is a long-life (up to five years depending on configuration),

deep-rated acoustic instrument fitted with high resolution pressure, sound velocity

and temperature sensors, all built around our 6G hardware platform and

Wideband 2 digital signal technology. AMTs run a fully automated logging regime,

gathering acoustic travel time (range) between neighbouring units, pressure,

sound velocity, temperature and tilt data at intervals defined by the user. The

integrated modem transfer rate of up to 9000 bps enables data to be extracted

in minimal vessel time, reducing operational costs, or alternatively we can supply

systems for an AUV, gateway buoy or USV to harvest data remotely on demand.

FETCH

Fetch supports the most demanding long-term seabed geodesy projects. It’s

available with many of the same features as AMT but thanks to its glass sphere

housing, it can be equipped with a high capacity primary lithium battery pack

(up to 505 Ahr), to support deployments in excess of 10 years. Additionally,

Fetch can be fitted with up to three high precision pressure sensors on a single

manifold, with scope for other internal and external sensors to be fitted as

required. Bluetooth and serial links are available for testing and configuration

before deployment. The ultra-low power platform only powers up sensors when

required and logs and timestamps the data to an internal SD memory card.

We also supply a GPS-Acoustic (GPS-A) payload for USVs that enables precise,

absolute positioning of Fetch deployed on the seabed.

FETCH AMBIENT-ZERO-AMBIENT (AZA)

Fetch AZA has been developed in response to the fact that despite the best

efforts of manufacturers, all pressure sensors drift to some degree similar to,

or even greater, than the actual subsidence signal – potentially between 2 and 20

cm/year in 2,000 metres of water. That’s why it’s important to regularly recalibrate

pressure sensors, but this obviously conflicts with the need for long term

deployments. AZA uses a patented system to periodically calibrate the high

pressure measurement sensor against a low pressure reference sensor at near

zero pressure. Because of the reference sensor accuracy and its very low drift,

the drift of the high pressure sensor is effectively eliminated.

UNTIL RECENTLY, THE INABILITY TO UNDERTAKE COST-EFFECTIVEGEODETIC MEASUREMENTS IN THE OUTERMOST AREAS OF OFFSHORESUBDUCTION ZONES, HAS BEEN A CRITICAL FLAW IN SEISMIC HAZARDASSESSMENT. IN RESPONSE, WE’VE WORKED CLOSELY WITH SOMEOF THE WORLD’S LEADING MARINE INSTITUTES TO ADAPT OURTECHNOLOGY TO PROVIDE NEW TOOLS THAT ARE NOW IN OPERATIONIN SEVERAL TECTONICALLY ACTIVE AREAS AROUND THE WORLD.

AMTFETCHFETCHAZA

SEISMIC EVENTS

DEEP OCEAN MONITORING

A tsunami wave in deep water creates a small but measurable change in pressure

that will be maintained for as long as 20 minutes. By monitoring any such changes,

our Bottom Pressure Recorder (BPR) will trigger an alarm that sends an acoustic

warning message to any suitably configured third-party surface buoy fitted with

a 6G transceiver. From there, it can be forwarded by satellite transmission to a

monitoring centre, where it can be correlated with other seismic sensors so that

a warning can be issued to vulnerable coastal communities if appropriate. This

means that the first warning of a tsunami, caused by a small variation in water

pressure on the seabed thousands of miles from shore, can be in the office of

the monitoring organisation within minutes.

TECHNOLOGY THAT YOU CAN RELY ON

The BPR is a customised version of our highly successful Compatt 6 acoustic

transponder, featuring Wideband 2 digital acoustic technology to provide robust

data transmissions even in difficult acoustic conditions. Operating in the LMF

(14 – 20 kHz) band, the system is supplied with a buoy-mounted transceiver,

but also works with any of our compatible surface dunkers or transceivers,

including a Ranger 2 LMF HPT. This two-way link also enables the unit to be

remotely configured, for example, if the operator wishes to put the unit into an

alert mode in anticipation of a tsunami. The instrument is optimised for low-power

consumption and long battery life for long term deployments, and can also be

supplied as a glass-sphere (Fetch). This can be deployed for up to 10 years without

needing to recover the instrument and in water depths down to 7,000 metres.

The BPR continuously monitors water pressure, saving data every 15 seconds

and in routine operation acoustically transmits this data hourly to a buoy on the

surface. Alongside this, the instrument runs the same NOAA algorithm as used

in the Deep-ocean Assessment and Reporting of Tsunamis (DART) system, which

compares the measured pressure with the predicted tidally modified pressure

based on the previous three hours history to correct for local conditions. If two

consecutive differences between both measurements exceed three centimetres,

the instrument goes into an alert mode and transmits a sequence of messages

containing high resolution pressure data to the surface over the next few hours.

SONARDYNE’S TSUNAMI DETECTION SYSTEM IS BASED ON OURWORLD-LEADING EXPERTISE IN PRECISION PRESSURE MEASUREMENTAND UTILISES OUR PROVEN COMPATT PLATFORM. CONSEQUENTLYYOU BENEFIT FROM AN EXTENSIVE DEPLOYMENT TRACK RECORDTHAT MEANS YOU CAN DEPLOY OUR SYSTEMS FOR MANY YEARSWITH COMPLETE CONFIDENCE.

OCEANCURRENTS

TWO-WAY TRAVEL TIME

The Pressure Inverted Echo Sounder (PIES) is a long-life sensor logging instrument

that accurately measures the average sound velocity through a column of water

from the seabed to the sea surface. It works by transmitting a wideband acoustic

pulse from its stable location on the seabed. This pulse is reflected off the sea

surface and returns to the seabed, where it is detected by PIES. The resulting data

enables two-way travel-time, often known as Tau (τ), to be calculated. At the same

time, an accurate measurement of depth (distance to the surface) is made using

a highly accurate internal pressure sensor. Using a robust empirical relationship

between τ and vertical profiles of temperature, salinity and density (derived from

historical measurements), arrays of PIES can be used in large scale observations

of ocean currents.

PIES is also capable of monitoring sea state (and by inference wind-speed) as

periods of low sea state are characterised by larger, stronger and more specular

reflection from the surface; while weaker, more diffuse returns result from high

sea states.

ROBUST DATA RECOVERY

As with our other in-situ instruments for ocean science, PIES is based on our

existing highly successful 6G hardware with Wideband 2 digital acoustic

technology, which also provides robust data transmissions even in difficult

acoustic conditions. Operating in the LMF (14 – 20 kHz) band, any of our

LMF surface dunkers or transceivers can be used to recover recorded data

at data rates ranging from 200 to 9,000 bits per second. These include our

LMF Ranger 2 USBL systems, which can also be used for positioning during

deployment and recovery. Nominally set up to transmit and record every five

minutes, PIES can be configured serially before deployment as well as using

the telemetry link once deployed.

GETTING THE MOST FROM YOUR PIES DEPLOYMENT

To achieve long term deployments, the ultra-low power platform only powers

up sensors when required and logs and timestamps the data to an internal SD

memory card. In its basic configuration, PIES can easily achieve deployments of

several months, while a glass-sphere variant with battery options ranging up to

a 505 Ah, is also available to support extended deployments of several years

depending on sampling interval configuration.

OUR PRESSURE INVERTED ECHO SOUNDERS (PIES) ARE POWERFULSCIENTIFIC INSTRUMENTS CAPABLE OF SUPPORTING OCEANCURRENT AND WATER/AIR INTERFACE RESEARCH. IN COMMON WITHOUR OTHER IN-SITU MONITORING INSTRUMENTS, PIES IS BASEDON OUR LOW-RISK 6G HARDWARE PLATFORM AND WIDEBAND 2DIGITAL SIGNAL TECHNOLOGY

SEARCH ANDRELOCATION

SPRINT-MAPPER

Advances in underwater laser, LiDAR and multi-beam technologies mean that

it’s now possible for an ROV (or manned submersible) to rapidly conduct highly

detailed surveys of wrecks, archaeological and benthic science sites. SPRINT-Mapper

underpins this capability with tightly integrated, acoustically-aided SPRINT inertial

and Syrinx DVL navigation, which is post-processed using our powerful software

tool for positioning and orientation of the laser/ camera, LiDAR or multi-beam

sensor data. Typical accuracies of one centimetre in the geo-referenced 3D point

cloud are achievable for single run line distances of around 20 metres. For these

projects, we can provide a complete equipment, planning and operations service.

SOLSTICE

Solstice is a Multi Aperture Sonar (MAS) that provides class-leading imagery

with co-registered swath bathymetry. Specifically designed for installation in

low logistic platforms, including AUVs, it has a compact design and low-power

consumption of only 18 Watts. MAS operates by dynamically focussing Solstice’s

32 elements across the whole 200 metre wide swath, which also produces

enhanced Signal-to-Noise Ratio (SNR). This results in highly detailed side-scan

imagery, accurately draped over the bottom topography, while on-board

processing supports Computer Aided Detection and Classification (CAD/CAC)

and Automatic Target Recognition (ATR).

DEEP MARKERS

We provide a range of instruments for fast and efficient routine or emergency

marking and relocation of underwater structures, diving bells and instruments on

the seabed – even in zero visibility. Where deep operations are involved (12,000

metres), our deep marker beacon, features a long life battery pack making them

ideal for use as permanent markers. Each transponder is individually encoded

enabling many transponders to be used on the same site to unambiguously

mark the location of your targets.

These beacons can be relocated using either our hand-held range and direction

device Homer-Pro, or ROV-Homer for ROVs. Both work by interrogating the

designated transponder to determine its range and direction and indicating the

direction in which to move. In the case of ROV-Homer, this is displayed on the

user’s PC, while with Homer-Pro, the information is displayed on the instrument.

BLACK BOX LOCATION

When a commercial aircraft is lost over water, the race begins to locate its flight

data and cockpit voice recorders. Our ROV-Homer, Homer-Pro and Ranger 2 USBL

systems be used to detect and localise emergency pinger signals.
